Hypothyroidism in newborns
«Gipotirioz" - a term meaning a decrease in activity of the thyroid gland.This condition is accompanied by a reduction in its level of hormones in the blood.
Congenital gipotirioz common in newborns more often.It occurs when the iodine deficiency in the diet, and can also be associated with thyroid hypoplasia, its inability to normal hormone formation.Sometimes the disease arises from the ingestion of certain drugs during pregnancy, mom.
Symptoms of congenital hypothyroidism in children
diagnosis of "congenital hypothyroidism" put both boys and girls.In most cases, infants with this problem is no different from other children.However, an attentive mother can already from the first days notice signs of low thyroid activity: baby sucks languidly, his big belly, dry skin, low body temperature, severe jaundice.And the cry of a baby special, hoarse.Face edema, especially the eyelids.Often these children revealed an umbilical hernia.
Early detection of hypothyroidism
Despite its small size, hormones produced in it, are involved in almost all processes in the body.The main function of the thyroid gland - to maintain normal metabolism in the cells of the body.
Thyroid hormones stimulate the metabolism, regulate every process in the body - breathing, eating, sleeping, exercise, as well as processes in the internal organs - from the heart to the working of the reproductive system.
Thyroid hormones are needed for normal mental and physical development.In addition to the growth hormone produced in the pituitary gland, they are responsible for the proper development of bones.
Lack of thyroid hormones in children leads to the cessation of growth and deficit of pregnancy - to the underdevelopment of the brain of a child.Since the growth of the fetus, and especially the development of the nervous tissue depends on thyroid hormones, children with hypothyroidism are born with lower weight at normal growth.
In the 70s developed a method of screening newborns for early detection of hypothyroidism.This has allowed to prevent irreversible brain damage and neurological disorders in children.
Observations for babies, identified in the course of this survey show that with proper treatment, intellectual and physical development of children did not differ from their peers development.
diagnose hypothyroidism before birth is very difficult - for the study of thyroid hormones necessary to amniocentesis (puncture and sampling the amniotic fluid with a long needle).
During pregnancy, it is necessary to explore thyrotropic hormones TSH and T4 on 8-12 week, when the influence of hormonal abnormalities in the fetus is particularly unfavorable.
Screening for congenital hypothyroidism
At the moment all newborns for 5-7th day of life determine the level of TSH.Its content in the blood of 20 nmol / L?Everything is fine!The level of 20-50 nmol / l - are regarded as questionable, and the study should be repeated.TTG above 50 nmol / l indicates hypothyroidism.
holding ultrasound of the thyroid gland, as well as determining the level of other thyroid hormones allows to confirm or refute the diagnosis.A more detailed survey is conducted only after the children 3 years (at that time already a relatively safe short-term interruption of treatment).
Treatment of congenital hypothyroidism in children
diagnosis of "congenital hypothyroidism" - not a sentence.Current treatment restores the necessary amount of hormones.With timely started treatment for mental and physical development of kids are no different from their peers.The criterion of the correctness of treatment - this is a normal age for TSH levels.
The cause of hypothyroidism may have different genetic and other factors, but none of them do not have to blame yourself (husband, mother in law, and other relatives).Experts believe a repeat of such a situation in a single family unlikely.Of course, in preparation for the next pregnancy should consult a geneticist.
